更新链接到具有 OneToOne 关系的用户的 UserProfile 的个人资料图像

Question

我能够在每次创建用户时自动创建用户配置文件，但我希望能够修改用户配置文件中的某些字段。

所以我的Model.py

def upload_path(instance,filename):
      return 'users/avatars/{0}/{1}'.format(instance.user.username, filename)

class UserProfile(models.Model):
      user= models.OneToOneField(User,on_delete=models.CASCADE, related_name='userprofile')

      Profileimage= models.ImageField(upload_to=upload_path, blank=True, null=True, default='user/avatar.jpeg')
      def __str__(self):
          return self.user.username

@ receiver(post_save,sender=User)
def create_user_profile(sender,instance,created,**kwargs):
     if created:
         UserProfile.objects.create(user=instance)

我的Serializer.py

class UserSerializer(serializers.ModelSerializer):
class Meta:
    model = User
    fields =['id', 'username','password','email']
    extra_kwargs={'password':{'write_only':True, 'required':True}}

def create(self,validated_data):
    user =User.objects.create_user(**validated_data)
    Token.objects.create(user=user)
    return user

class UserProfileSerializer(serializers.ModelSerializer):
user=serializers.SlugRelatedField(queryset=models.User.objects.all(),      slug_field='username')
class Meta:
    model =models.UserProfile
    
    #lookup_field = 'username'
    fields= '__all__'

我的view.py

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    lookup_field = 'username'


class UserProfileViewSet(viewsets.ModelViewSet):
    
    queryset = UserProfile.objects.all()
    serializer_class = UserProfileSerializer

使用邮递员我得到错误：django.db.utils.IntegrityError：唯一约束失败：api_userprofile.user_id

Answer 1

所以添加后

    def put(self, request, *args, **kwargs):
           return self.update(request, *args, **kwargs)

我能够更改我想要的字段。
